This study introduces TROPIX, an AI system combining case-based reasoning (CBR) and association-based reasoning (ABR) to enhance disease diagnosis and treatment selection in Nigerian healthcare. It addresses limitations in resources by leveraging past medical cases for improved clinical decision-making.

Area of Science:

  • Artificial Intelligence in Medicine
  • Health Informatics
  • Clinical Decision Support Systems

Background:

  • Limited laboratory facilities, medical doctors, and expertise in rural/semi-urban Nigerian clinics and public hospitals hinder effective healthcare delivery.
  • The TROPIX project aims to address these challenges through an innovative computational approach.

Purpose of the Study:

  • To present a novel computational framework integrating case-based reasoning (CBR) and association-based reasoning (ABR) for disease diagnosis, validation, and therapy selection.
  • To improve the accuracy and efficiency of diagnostic processes in resource-limited healthcare settings.

Main Methods:

  • Employs a classification method using similarity/dissimilarity aggregate functions and matched vector functions (MVF) for initial disease diagnosis.

Related Experiment Videos

  • Utilizes evidence ratio factors (ERF) to resolve tied match cases.
  • Integrates a case-based reasoning (CBR) model for validating tentative diagnoses by reusing past similar cases.
  • Organizes the case library using singular value decomposition (SVD) for efficient data retrieval and employs domain-specific case-object properties.

    • Main Results:

    • The proposed system provides a validated disease diagnosis and facilitates therapy selection by effectively filtering data and enhancing the case base.
    • Demonstrates the utility of combining statistical and case-based reasoning for complex diagnostic tasks.

    Conclusions:

    • The TROPIX system offers a practical solution for improving healthcare delivery in resource-constrained environments by enhancing diagnostic capabilities.
    • The integration of CBR and ABR, coupled with advanced data organization techniques, shows significant potential for clinical decision support systems.
